Abstract

The invention discloses a scrapable formaldehyde closed film and a preparation method thereof. The film comprises the following components in parts by weight: 1-20 parts of polyvinyl alcohol, 100 parts of deionized water, 1-50 parts of water-based acrylic resin, 0-1 part of a defoamer, 0-10 parts of an emulsifier, 0-10 parts of a plasticizer, 0-10 parts of other coating assistants, 0-30 parts of a silica sol, 0-50 parts of powder filler and 0-10 parts of a formaldehyde purifying material. According to the film, by mainly using good gas barrier property and film forming property of the polyvinyl alcohol thin and matching with various coating assistants and a less amount of formaldehyde purifying material, not only is the attractive thin formed on the surface of wooden furniture, but also formaldehyde is thoroughly closed and removed. By adjusting the strength and water resisting property of the film, the film not only affects daily article placement in wooden furniture, but also further realizes the purpose that a wet mop is used for removal after close treatment without any traces and influence on attractiveness of the furniture.

Description

technical field [0001] The invention belongs to the field of indoor air purification and treatment, and relates to a purgable formaldehyde sealing coating film and a preparation method thereof, especially for sealing and treatment of indoor formaldehyde release sources while ensuring the appearance of wooden furniture. Background technique [0002] The impact of formaldehyde on the environment and health has long been recognized by people. However, a recent study shows that formaldehyde has become the first class of carcinogens, and long-term exposure to formaldehyde will lead to gene mutations. Formaldehyde can cause damage to human skin, respiratory tract, and internal organs, anesthetize the central nervous system, and cause pulmonary edema, hepatic coma, and kidney failure. The World Health Organization confirms that formaldehyde is a teratogenic, carcinogenic substance, and is a source of allergies. In building decoration, artificial boards such as plywood, blockboard,...
